Answer:
Total área: 9+9+8+6= 32 mm^2
Step-by-step explanation:
Square = 3x3 = 9mm^2
Triangle= Heigh: sqrt (3^2+3^2) = 9 and base=3
A = (9x3)/2 = 9mm^2
Rectangle= 4x2= 8mm^2
Triangle (high: 5-2=3)
(4x3)/2 = 6mm^2
Total area
There was 30 in each box until he gave 8 away so no there is probably 28 in each box
sorry if i am wrong
4X - 8 = 112
Solve as a simultaneous equation maybe?
f(x) + g(x) = 2x or x/(x-6) + y =2x
and then solve so it becomes 2x^2 + 5x =y
then factorise into brackets or use quadratic formula
Answer:
y=ax+1
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
y=ax+1
